You have 50 red marbles and 50 blue marbles. Your have two jars. If I am to choose a jar at random, what ratios of marbles would you put in each jar to increase the probability of me choosing a red marble?

I would put 1 solo red marble in one of the jars and all other marbles in the second jar. Probably of picking a red marble in such case should be: (0.5*1) + (0.5*49/99) = 0.747.
